  65           This is the processor type of your CPU.  This information is
  66           used for optimizing purposes.  In order to compile a kernel
  67           that can run on all 32-bit PA CPUs (albeit not optimally fast),
  68           you can specify "PA7000" here.
  69
  70           Specifying "PA8000" here will allow you to select a 64-bit kernel

 119           Enable this if you want to support 64bit kernel on PA-RISC platform.
 120
 121           At the moment, only people willing to use more than 2GB of RAM,
 122           or having a 64bit-only capable PA-RISC machine should say Y here.
 123
 124           Since there is no 64bit userland on PA-RISC, there is no point to
 125           enable this option otherwise. The 64bit kernel is significantly bigger
 126           and slower than the 32bit one.

 131           This enables support for systems with more than one CPU. If you have
 132           a system with only one CPU, like most personal computers, say N. If
 133           you have a system with more than one CPU, say Y.
 134
 135           If you say N here, the kernel will run on single and multiprocessor
 136           machines, but will use only one CPU of a multiprocessor machine. If
 137           you say Y here, the kernel will run on many, but not all,
 138           singleprocessor machines. On a singleprocessor machine, the kernel
 139           will run faster if you say N here.
